Zenyard RE Agent

Zenyard RE Agent is an AI-powered reverse engineering tool designed to help security researchers analyze complex binaries efficiently.

The agent performs end-to-end analysis of entire binary files, including large ones, providing accurate insights grounded in full-binary context rather than operating on isolated code snippets. It reconstructs structs using signals from the entire codebase, producing accurate layouts and field names that reflect real usage across functions and modules.

Zenyard supports high-level language decompilation, including Swift, rebuilding code into a form that closely resembles the original source. Decompiled code is transformed into source-like output with documentation and meaningful names for functions, parameters, and variables.

A built-in copilot feature allows researchers to ask plain-language questions to surface relevant functions, behaviors, and data flows within a binary. Users can also control the level of interpretation, ranging from conservative (minimal renaming, decompiler-faithful output) to speculative (deeper intent recovery with richer types and higher-level structure).

The tool integrates directly into existing decompiler workflows. Deployment options include cloud-based SaaS, private cloud, and fully on-premises installations, including air-gapped environments.
